transformations of alcohols under solvent-free reaction conditions (SFRC) and under highly concentrated reaction conditions (HCRC) in the presence of various solvents were studied in order to gain insight into the behavior of the reaction intermediates under these conditions. Dimerization, dehydration and substitution were the three types of transformations observed with benzylic alcohols. Dimerization

constituent organic linker. For ActB-Tol, its LA strength even approaches that of the commonly used molecular LA, B(C6F5)3. Most notably, ActBs can act as heterogeneous LA catalysts in hydrosilylation/deoxygenation reactions with various carbonyl substrates as well as in the gas-phase dehydration of ethanol. These studies reveal the potential of ActBs in catalytic applications, showing (a) the possibility
基于硼烷簇的多孔共价网络,称为活化硼烷(ActB),是通过十硼烷(14)(nido -B 10 H 14)和选定的碳氢化合物(甲苯,ActB-Tol;环己烷,ActB- cy Hx;和正己烷,ActB- n Hx )在厌氧条件下。这些无定形固体粉末表现出不同的结构和路易斯酸(LA)特性,这些特性根据组成有机连接体的性质而变化。对于ActB-Tol来说,其LA强度甚至接近常用的分子LA,B(C 6 F 5 ) 3。最值得注意的是,ActB可以在各种羰基底物的氢化硅烷化/脱氧反应以及乙醇的气相脱水中充当非均相 LA 催化剂。这些研究揭示了ActB在催化应用中的潜力,表明 (a) 通过改变材料的组成来调整氢化硅烷化/脱氧反应中催化反应结果(选择性)的可能性,以及 (b) 对乙醇脱水的极高活性,超过了常用的 γ-Al 2 O 3在 240 °C 连续运行 17 小时期间实现了约 93% 的稳定转化率和约
